"Although Chu has three households, if Qin is destroyed, Chu will definitely die" comes from "Historical Records·The Chronicles of Xiang Yu".

"Historical Records of Xiang Yu": "Qin destroyed the six kingdoms, and Chu was the most innocent. Since King Huai entered Qin, he has not rebelled, and the people of Chu have pitied him to this day. Therefore, Duke Nan of Chu said, 'Although Chu has three households, "If the Qin Dynasty is destroyed, the Chu Dynasty will be destroyed."

In fact, this famous saying originated from the era of resistance to the violent Qin rule. In addition to representing an emotional and firm belief, it is also incredibly consistent with the evolution of history. The process matches. It a priori and incomparably correctly predicted the true meaning of the subjugation of Qin: that is, the cause of the subjugation of Qin started in Chu and was finally completed in Chu. And just in terms of the fact of the fall of Qin, this famous saying has double fulfillment. First of all, although the great cause of the overthrow of Qin was achieved by the people of the world, the three Chu people who really played the decisive role were Chen Sheng, Xiang Yu, and Liu Bang. Secondly, the decisive battle to overthrow Qin was fought in the area of ??Sanhushui (now west of Linzhang, Hebei Province). Chu general Xiang Yu led his army to defeat the main force of the Qin army and accepted its surrender. From then on, Qin's demise became irreversible. The following is an examination of the fulfillment of this famous saying based on historical records.

The Chu State has a vast territory and rich resources, and its people are strong-willed. In addition, when King Huai of Chu entered Qin, he could not return to Qin after he died in Qin. The Chu people hated the Qin State, so there is a saying that "although Chu has three households, it will be destroyed." Qin must be Chu."

According to "Historical Records of Xiang Yu", as early as when King Huai of Chu died in Qin, Duke Nan of Chu said: "Although Chu has three households, if Qin is destroyed, Chu will definitely die." This prediction was a priori and extremely correct. The true meaning of the subjugation of Qin: that is, the cause of subjugation of Qin started in Chu and was finally completed in Chu. And just in terms of the fact of the fall of Qin, this famous saying has double fulfillment. First of all, subsequent history also confirmed Nangong's theory. When they raised their arms in Daze Township, the world responded that Chen Sheng was from Chu, and the regime he established was called "Zhang Chu". Xiang Yu, who led the people from Jiangdong to cross the river and became the main force against Qin, was also from Chu, and the regime he established was called "Western Chu" . Liu Bang, who led the heroes, brought order to the country, and established an unprecedented unified Han Dynasty, was also from Chu. Liu Bang's advisers and generals, except for Zhang Liang and a few others, were also heroes of Chu.

There are two explanations for this sentence in the historical records. One refers to the three major surnames of Chu State, and Sanhu refers to the three major surnames of Chu State: Zhao, Qu and Jing. The other means that even if there are only three families left after the fall of Chu, they will surely destroy Qin. This means that the people of Chu hate Qin very much.
